APOBEC3B and reading: After a series of analyses, we observed that the infiltration value of cancer-associated fibroblasts in ESCA, GBM, HNSC-HPV−, LGG, PCPG, rectum adenocarcinoma (READ), TGCT, and THCA type tumors were positively correlated with the expression level of APOBEC3B, but negatively correlated with BRCA and HNSC-HPV+ tumor types (Fig. 4a).
